They report the president said he had offered Nalyvaichenko a position of External Intelligence Service head. At the same time, Poroshenko said, Nalyvaichenko confirmed his SBU head resignation on Saturday. "Udar faction deputies [Kyiv's mayor Vitalii Klitschko party - ed.] offered to discuss the matter at the faction meeting, to which Poroshenko said the deputies could meet Nalyvaichenko whenever they wanted to," the source is quoted saying.

Earlier, SBU head adviser Lubkivskyi wrote on his Facebook page that the Presidential Administration did not allow Nalyvaichenko to travel to the U.S. with his Russian aggression evidence report due to his interrogation by the Prosecutor's Office.

Nalyvaichenko was interrogated on his statement of June 12 about former deputy Prosecutor General Anatolii Danylenko receiving 'illegal income' from BRSM-Nafta oil depot near Vasylkiv, the Kyiv region, where the fire has been raging since early last week, and was its co-owner. The SBU head also announced Danylenko's possible detainment on Tuesday.
